One million

Write the million number (1000000) by using only 9 numbers and algebraic operations plus, minus, times, divided, powers, and squares. Find at least three different solutions.

Correct result:

a =  1000000
b =  1000000
c =  1000000

Solution:

$a=999999+9\mathrm{/}9=1000000$

$b=99999\cdot (9+9\mathrm{/}9)+99\mathrm{/}9-9\mathrm{/}9=1000000$

$c=(9+9\mathrm{/}9{)}^{(9+9+9+9+9+9)\mathrm{/}9}=1000000$
